PHP – Loops – while – do…while – for – foreach
while
<?php
$x=1;
while($x<=5) // It executes the code as long as the specified condition is true.
{
echo "The number is: $x <br>";
$x++;
}
?>
do…while
<?php
$x=1;
do
{
echo "The number is: $x <br>";
$x++;
}
while ($x<=5) // It executes the code as long as the specified condition is true.
?>
NOTICE:
while -> 1. condition verification 2. code execution
do…while -> 1. code execution 2. condition verification
for
<?php
for ($x=0; $x<=10; $x++)
{
echo "The number is: $x <br>";
}
?>
foreach
The foreach loop works only on arrays, and is used to loop through each key/value pair in an array.
<?php
$colors = array("red","green","blue","yellow");
foreach ($colors as $value)
{
echo "$value <br>";
}
?>
